Abstract：According to the characteristics of "gaining profit in post" and "losing profit in front" of the parallel mining pit ditch-dumping,bridging is put forward to connect the transport channels between the end slope and inner dumping to reduce the stripping in row distance.The main parameters of the bridge are designed according to the end wall conveyor bridge shape,moving distance of the bridge is proposed.The economic benefit equation of moving distance is set up.Based on the example in Haerwusu and Heidaigou Open-Pit Mine,the end slope internal dumping ditch bridge optimal advancing distance is calculated,which is 260.7m.
